I have an iBook G4 1.42Ghz with 1.5GB of RAM. I have noticed lately (past month) that it has been slowing down...A BIG SLOW DOWN. You would think even with 1.5GB of RAM, there should be no slow down, but I guess I was wrong. I did a Hardware test using the install disks and everything is OK. Should I erase my HD and just re-install OS X? If you guys got any other suggestions please let me know. Any help would be great!

I will install a freshcoat tonight. But, when I install, should I totally erase the hard drive on Disk Utility and then just install using the install CD's? Or just put the disk in and copy over my stuff? I already have all the stuff saved on my external.

I have never wiped out a hard drive on a Mac. Can you guide me through it? Or perhaps Apple has a guide on how to erase everything on the drive? I select both drives in DU (the name of the HD and the name I gave it, in my case iBook HD), but it does not give me the "erase" option.

I just re-installed everything about 1 hour ago and I just finished putting all my stuff from my external to my iBook. So far it has been running much much smoother, no problems. But, I did notice that I have a much "cooler" iBook (temp. wise). Usually when running, my CPU is about 125-155*F, but right now with Safari, Mail, DB, and iTunes; my CPU is at 98*F.
Thanks for all the help guys!!
